i want to do a research about planning mitigation for disabilities, especially for physical disability. I want to know the needs or the facilities for them during disaster
You can explore a research documentation from Handicap International- http://www.handicap-international.de/fileadmin/redaktion/pdf/disability_management.pdf
Also have time to read this research paper- http://www.preventionweb.net/files/9706_DisasterManagement.pdf
This publication may not be specifically on physical disability but should be useful regardless "Children with disabilities and disaster preparedness: a case study of Christchurch" http://www.tandfonline.com/doi/full/10.1080/1177083X.2015.1068185
